Super73 Z1 72V vs 52V? 1/4 mile times! 40MPH?! Which way should you go?

Today we have my Z1 which I just picked up not long ago.
Stock was 20mph, and would hardly move out of its own way.
I decided it was time for a upgrade, which meant deciding on which voltage to go on, previously I have tried both. And already have moved forward with my 72V build.
I don’t make or sell any parts or battery’s, or any bike parts. Just looking to share my findings!
Watch the video? Check out the data. Following along for more videos.
For anyone who wants to know what controller and throttle I used check out my other video with the Z1 72V.
Have any advise? Suggestions? Or questions? Comment below, if you enjoyed the video share it! And subscribe for more E-Bike content.
Power output battery’s are capable of.
52v pack
58v fully charged 50 amp bms so around 2900 watts.
72v pack fully charger 84 volts 30 amp bms. 2520 watts.
So the 52v pack has more overall power.
The controller is a 50 amp controller so should of been able to take full advantage of the 2900 watts,
Keep in mind both BMS can output more power during bursts. Both videos during take off I am sure we around 3000 watts, how ever soon with added shunts I will be able to monitor this data properly.

This is awesome! Glad to see another high powered Z1

[@BuildItTuneItEV]

Thanks man, thinking of going phase runner and DD45. But it’s been so much fun as is, which I had some field weakening with this controller.

[@BuildItTuneItEV]

What’s your setup?

Mike Adkins 72v 60amp controller with a 3kw hub

@@Rayalas323 big boy stuff🤟🤟

[@Rayalas323]

Mike Adkins 72v is the way to go!

[@naimadoszeros6210]

Think about 52V to my SUPER73 ZG for about 100km range.The serial motor looks very friendly to do that.Nice video and you got my SUB Bro

[@BuildItTuneItEV]

Thank you

[@JerseyStyle7]

I just ordered the same exact color I was going to get the RX but I like the looks of this one better also subscribed👍😎😎

[@jmez927]

Excellent!!! A proper mod with good speed. Keep grinding and growing

[@JCNY718]

Very cool! This is my favorite super73 bike (well the only one I would buy) would def mod it like your bike.

[@BuildItTuneItEV]

Thanks man, it’s such a cool bike. And as you can see within a week or two we are here! I plan to post up anything I design for the bike. So if you have a 3D printer follow along.

[@JCNY718]

@@BuildItTuneItEV how much range can you get with the 52v? I’m currently riding an Onyx RCR but I wouldn’t mind getting a project bike.

[@BuildItTuneItEV]

@@JCNY718 I diy most of most own battery since learning how to. If using the 52v pack I showed in video I have went 25 miles at around 25/30 mph with plenty left. 52v was not much slower, how ever I honestly did less testing with 52v since I really wanted that 40mph. With all hub motors, and we are speaking with general tuning. More volts= higher top speed. So if you can give up some top end, and use a 14s(52v) with high P you will get very long distance. Watt hours is what determines the final distance.

[@zoobiewa]

You say that torque goes DOWN with increased voltage? I thought the torque of the motor is directly proportional to the square of the supply voltage. So like, if voltage decreases, torque will decrease as well as RPM. But you are saying because the 52v allows 50 amps vs the 72v that allows just 30, that also plays into the torque. Ahh. Gotcha. I think I answered my own question, lol.

[@BuildItTuneItEV]

Only because I was using a lower amperage 72v battery here. 72v offers more tq if similar wattage.

[@phatalextran]

nice. question is that it is safe for the motors for 1/4 miles run is not bad but how about if you riding it all day

[@BuildItTuneItEV]

1/4 mile run is flooring it the entire run. Most my driving around is just cruising and much easier on it. How ever I upgraded motors for more speed now so I can say how long stock would of lasted

[@SultaNNNNNNNNN]

@@BuildItTuneItEVwhat kind of motor did you put?

[@Krisjewer9513]

Good video do u have the link were u got the controller from?

[@MikeMike-qb3iz]

👍🚀

[@BrettsGarage]

Cool Vid. Would like to see a step by step on a battery build.

[@BuildItTuneItEV]

I need to get a little more practice but I hope to do one.

[@TannerSherwood-m6o]

how do i make my super 73 z1 go faster?

[@JerseyStyle7]

Awesome speed😎👍👍👍👍👍👍👍

[@andymartinez1426]

Interesting 🧐

[@nelsons.reviews]

Are you not afraid of burning out the 500 watt motor??

[@BuildItTuneItEV]

No

[@Aeverage513]

im looking to upgrade my z1. can you leave a link to your controller.

[@gabrielbotton9081]

yo whered you get the cool throttle from?

[@dantoniorobinson21]

Hold on how that battery without speed display?

[@davidmahat4967]

How can I do that?

[@aloharc8oh8]

This is awesome! I like upgrade my z1 to 52v but is it worth it? My top speed now is 28mph with the speed hack

[@gmeister03]

Are you able to use a qs motor? 72v with 100 amp bms would be fun

[@BuildItTuneItEV]

Yes, Now I have QS205 V3 2.5T With 200amp controller. Much more fun.

[@gmeister03]

@@BuildItTuneItEV 200…. That’ll work

[@BuildItTuneItEV]

​@@gmeister03 finishing up the tuning now, been slacking on updates. I did some custom frame mods. After doing the new hub I found it needed some extensions. Added 7" extensions to the frame and its much better.

[@THEPAINOFITALL]

Which video has controller info 😔

[@BuildItTuneItEV]

Any amazon 48V controller that supports brushless will work!

[@JerseyStyle7]

Did you have to clip the white wire in the controller to go above 20mph, besides the battery packs ???🤔

[@skewedfpv629]

Would you be willing to share the stl for the bbshd + phaserunner cover?

[@BuildItTuneItEV]

Yes, I am working on final revision with gasket to upload.

[@skewedfpv629]

@@BuildItTuneItEV Thank you for sharing! And good thinking on the gasket. Have you noticed any heat build up yet?

[@BuildItTuneItEV]

@@skewedfpv629 only on the motor on long distance road. Controller runs better here than where mounted previously. Using field weakening creates some heat. Also I run low tire pressure.

[@skewedfpv629]

@@BuildItTuneItEV that sounds very promising! I noticed a bit of heat in the motor as well after some hill runs through snow, controller side of the case stayed cool on my end too.

[@lambomercy90]

So all I need is a bigger battery to make it go faster?

[@ebiker66]

Did you change out the original 36 volt controller?

[@BuildItTuneItEV]

Yes

[@sexysean2444]

Hi what app do you use for monitoring speed

[@BuildItTuneItEV]

Dragy!

How much watts was it?

[@BuildItTuneItEV]

1500W controller here.

[@miguelacorrea1]

Change controler the 48 a 72 volt

[@BuildItTuneItEV]

Huh?

[@matelslug1]

wow, so it all comes down to controller amps, 72v vs 52v not much of a difference there...

[@BuildItTuneItEV]

A smaller amp and wattage battery was able to out preform the higher amp lower voltage battery. And since than I have build a 60 amp 72v battery and it does wheelies lol.

[@michaelmatthew4367]

That's not true I have a 52 volt 21 amp battery with a 52 tooth sprocket and the smallest Shimano 9 speed cassette and I can easily do 75 miles a HR on it it's so fast I never passed level 7 or 7th gear . On level 3 and 7th gear I can hit spears almost 50 miles an HR. I have the bafang 1000 watt high performance midrive your bike is junk I built my own.🤣😂😋😝😎

[@BuildItTuneItEV]

This is a Hub motor, so gears do not matter. I built my own bike as well. You came here to brag about your junk? Cancer?

[@crinsen]

either my bike is more then 3kw on stock contorller or the controller and battery are limited on ur bike
